There’s comfort in quiet. You can feel it the minute you put them on. The soft, plush cushions seal you in. You press the button and whoosh — the world fades, the music starts, and it’s love at first listen. 

  • Proprietary active noise cancelling technology to control how much outside world you hear
  • Made with custom cast metal pivot points, impact-resistant headband, and plush synthetic leather

  • Lithium-ion rechargeable battery
  • Up to 22 hours of audio playback (with Noise Cancelling on)
  • Continue to listen to your source even if the battery power is depleted

  • Multi-function button  for play/pause, answers/ends calls, access to virtual assistant, volume +/- buttons, Quiet/Aware Mode button
  • Active noise cancelling relies on a sophisticated proprietary electronics approach, using microphones both inside and outside the earcups to monitor the sounds around you and instantly produces an opposite signal to cancel the noise
  • Passive noise reduction is achieved by the combination of earcup fit, design, and clamping force of the headband
  • Aware Mode – turn on the external microphones and feed ambient sounds into the headphones, enabling awareness of the sounds in the environment, such as cars and emergency vehicles, while still enjoying audio content
